A client is recovering from total hip arthroplasty.
What intervention should the nurse prioritize to prevent skin breakdown?

Choice A rationale

Monitoring cardiorespiratory status is the highest priority for an electrical burn patient because electricity frequently causes cardiac arrhythmias or arrest. The heart's electrical conduction system is extremely sensitive to external currents, which can trigger ventricular fibrillation. Additionally, the path of the current can cause respiratory paralysis or delayed cardiac issues. Immediate and continuous EKG monitoring is essential to detect and treat life-threatening dysrhythmias that may not be immediately apparent upon initial physical inspection of the skin.

Choice B rationale

Assessing circulation to the extremities is important because electrical burns can cause internal tissue damage and swelling, leading to compartment syndrome. However, this is secondary to the immediate threat of cardiac arrest. While the nurse must check peripheral pulses and capillary refill to ensure the limbs are perfused, the systemic stabilization of the heart and lungs takes precedence. Compartment syndrome is a serious complication, but it develops over hours, whereas cardiac rhythm disturbances can be fatal instantly.

Choice C rationale

Evaluating electrolyte balance is necessary because extensive tissue damage from an electrical burn releases large amounts of potassium into the bloodstream, potentially causing hyperkalemia. Normal potassium ranges are 3.5 to 5.0 mEq/L. While hyperkalemia can lead to cardiac issues, the direct effect of the electrical current on the heart's conduction is the more immediate concern. Electrolyte monitoring is a vital part of the ongoing management but follows the initial assessment of the patient's active heart rhythm.

Choice D rationale

Checking for signs of infection is a long-term management goal rather than a critical aspect of the initial assessment. Infection usually takes days to develop. In the immediate aftermath of an electrical injury, the focus must be on the invisible internal damage caused by the current's path through the body. Although skin entry and exit wounds should be cleaned, the life-threatening risks are physiological and internal, necessitating a focus on vital organ function and hemodynamic stability.

Choice A rationale

A sunburn is the most common example of a first-degree, or superficial, burn. This type of injury only involves the epidermis, the outermost layer of the skin. It is characterized by redness, pain, and heat without the formation of blisters. The skin remains intact, and the injury typically heals within three to six days without scarring. This level of burn does not require intensive fluid resuscitation because the skin's barrier function is largely preserved.

Choice B rationale

Excessive scarring, such as keloids or hypertrophic scars, is a complication associated with deeper burns that involve the dermis, such as second-degree or third-degree burns. First-degree burns do not damage the deeper layers of the skin where collagen production is significantly disrupted, so they do not result in significant scarring. Scarring indicates that the injury reached the dermal layer, triggering a more complex inflammatory and proliferative healing response that is absent in superficial burns.

Choice C rationale

Blistering is the hallmark of a second-degree, or partial-thickness, burn. This occurs when the injury extends through the epidermis and into the underlying dermis, causing fluid to accumulate between the layers. First-degree burns are strictly limited to the epidermis and do not produce blisters. Because second-degree burns involve deeper tissue damage and fluid shifts, they are more painful and carry a higher risk of infection compared to the simple redness seen in a first-degree burn.

Choice D rationale

Blackened, charred, or leathery skin is indicative of a third-degree, or full-thickness, burn. In these injuries, the epidermis and the entire dermis are destroyed, and the damage may extend into the subcutaneous fat or muscle. These burns are often painless because the nerve endings have been destroyed. This is a severe medical emergency that is far more advanced than a first-degree burn, which only causes minor damage and maintains the sensory function of the skin.
